Driver Side Rear Damping That Holds Up Under Load
The ICON 76552RD is the driver side rear VS 2.0 HD piggyback reservoir shock built for 2011-2026 GM 2500HD and 3500HD trucks running 0 to 1.5 inches of rear lift. Sold as the companion to the passenger side 76552RP, this shock uses a remote piggyback reservoir to add oil volume and nitrogen charge so damping performance stays consistent whether the truck is empty, loaded down, or pulling a trailer. Every internal valve stack is tuned specifically around GM HD spring rates rather than a one size fits all curve.
Key Features
- Vehicle specific valving tuned for the GM 2500HD and 3500HD rear suspension
- Piggyback remote reservoir increases oil volume and improves heat dissipation
- 6061 aluminum shock body resists corrosion and reduces unsprung weight
- 7/8 inch chrome plated shaft holds up to repeated heavy payload cycles
- 100 percent rebuildable and revalveable for long term serviceability
- Designed specifically for the driver side rear mounting position
